From the project

Monorepo for all schematics and PCB designs

We design our PCBs in KiCad (version 8+).

Files that should be in this repo, under version control: - Project files (.kicadpro). - Schematic files (.kicadsch). - PCB files (.kicadpcb). - Custom footprints (.kicadmod). - Custom symbols (.kicadsym). - Footprint library tables (fp-lib-table). - Symbol library tables (sym-lib-table). - 3D models of components (.step files). - Simulation code (e.g. .asc` files from LTSpice).

8 Channel Sensor Hub: common questions

What microcontroller does the 8 Channel Sensor Hub use?

The 8 Channel Sensor Hub is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the 8 Channel Sensor Hub PCB?

The 8 Channel Sensor Hub measures 58.5 × 57.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the 8 Channel Sensor Hub?

96 components, from 52 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 8 Channel Sensor Hub design files?

From the sufst/pcb repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the 8 Channel Sensor Hub design in my own project?

Yes, under the terms of its GPL-3.0 license, which sufst chose for the repository.

Can I test firmware for the 8 Channel Sensor Hub without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
